Nylon Fiber Filament Yarn & Chips Manufacturers

Nylon fiber is a general term for a class of fibers with -Co -NH- groups on macromolecular chains. The main varieties commonly used for aliphatic polyester amine are polyamide 6 and polyamide 66, and our commodity name is nylon 6 and nylon 66. Nylon fiber is mainly filament, and a small amount of short fiber is mainly used for blending with cotton, wool or other chemical fiber. Polyamide filament is widely used in deformation processing to manufacture stretch silk, as woven or knitted raw materials. Nylon fiber is generally spun by melt method. The strength of polyamide 6 and polyamide 66 fibers is 4 ~ 5.3cN/dtex, and the high strength polyester fibers can reach more than 7.9cN/dtex. The elongation rate is 18% ~ 45%, and the elastic recovery rate is more than 90% at 10% elongation. According to the test, the wear resistance of nylon fiber is 20 times that of cotton fiber, 20 times that of wool and 50 times that of viscose. Fatigue resistance of all kinds of fibers first. It is widely used in the civilian processing of socks and other blended products to improve the wear-resistant fastness of fabrics. However, the low modulus of polyamide fiber is inferior to that of polyester fiber, which limits the application of polyamide in the field of clothing. The life of nylon cord is 3 times larger than that of viscose, and the impact absorption energy is large, so the tire can drive on the bad road surface, but because the nylon cord elongation is large, the tire deformation is flat when the car stops, and the car beats badly in the early starting period. Therefore, it can only be used for the tires of freight cars, and should not be used for the tire cord of passenger cars.

The surface of nylon fiber is smooth, the fiber friction coefficient is very high without oil agent, and the storage of nylon oil agent is easy to fail, and the textile processing also needs to add oil agent again.

The moisture absorption of nylon fiber is higher than that of polyester. Under standard conditions, the moisture recovery rate of nylon 6 and 66 is 4.5%, which is second only to Vinylon among composite fibers. Good dyeing performance, available acid dyes, disperse dyes and other dyes dyeing.
